From 592570c950fb455226cd255603de7cede2be83e6 Mon Sep 17 00:00:00 2001 From: Helge Deller Date: Fri, 8 Apr 2016 22:10:35 +0200 Subject: parisc: Handle R_PARISC_PCREL32 relocations in kernel modules Commit 0de7985 (parisc: Use generic extable search and sort routines) changed the exception tables to use 32bit relative offsets. This patch now adds support to the kernel module loader to handle such R_PARISC_PCREL32 relocations for 32- and 64-bit modules.
